Sagot :
Answer: True
HIV infects a type of white blood cell in the body's immune system called a T-helper cell (also called a CD4 cell). These vital cells keep us healthy by fighting off infections and diseases. HIV cannot reproduce on its own. Instead, the virus attaches itself to a T-helper cell and fuses with it (joins together).
Explanation:
T-cells, the thymus cells, work in a similar way but destroy infected cells rather than manufacture antibodies. In HIV infection, the body mounts a very strong antibody response in the first few weeks that partially works, bringing the viral load down from millions to, on average, about 50,000 copies/ml.

The answer is true...
Explanation:
HIV infects a type of white blood cell in the body’s immune system called a T-helper cell (also called a CD4 cell). These vital cells keep us healthy by fighting off infections and diseases.
HIV cannot reproduce on its own. Instead, the virus attaches itself to a T-helper cell and fuses with it (joins together). It then takes control of the cell’s DNA, makes copies of itself inside the cell, and finally releases more HIV into the blood. HIV will continue to multiply and spread throughout the body – a process called the HIV lifecycle.
In this way, HIV weakens the body’s natural defences and over time severely damages the immune system. How quickly the virus develops depends on a person’s general health, how quickly they are diagnosed and start antiretroviral treatment, and how consistently they take their treatment
